Water pumps for field irrigation run on diesel engines or require a lot of electricity. Most pumps are mobile and are used where they are needed. Solar-powered models have been around for some time, but have the disadvantage that the modules are permanently mounted so that an expensive module with its own electric pump was required for each well hole. This was to be changed by a mobile solar system. The self-construction has now passed the first test. For transport, the modules are compactly stowed on an existing trailer that is no longer needed and are taken to the place of use with the tractor. There the two panel supports are unfolded via a rail system similar to a drawer, connection to the pump brought along, ready. Solar is thus competitive with mobile diesel pumps in terms of practical handling.
